vices, of which the following is a specification.

My invention relates to new and useful improvements in car doorlocking devices and has for an object to provide a locking device that is especially adapted for use on freight cars having the ordinary drop bottom doors, or on hopper: cars where the hoppers and doors are angularly disposed with relation to the car floor.

As is well known to those skilled in the art, the closing of car doors of theswinging or drop type, is easily accomplished with the exception of the final closing movement, as many ofthe doors become distorted or warped from the hard usage incident thereto, or particles of coal or other matters become .clogged between the hingededge of the door and the frame Vso that. it is necessary to exert relatively greatI pressure on the door at the last few inches-of theclosing movement. y

I have also found in practice thatit' is desirable to provide a locking ldevice wherein the door may be lifted by hand toa temporary supported partly closed position, and from which position the door may be then pried or forced into its final close and locked position.

Another object, therefore, of tliepresent invention is to provide brackets ineach of which is pivotally mounted a hook; thel brackets being rigidly secured to the sides of a hopper, while a rodis secured tothe bottom ofthe door, which rod is provided with offset ends designed to be engagedfby the hooks pivoted to the hopper sides. A lug is also disposed on each siderof the car bottom, near its outer end, so that when yit is desired to close the V`door theoffs'et ends of the rod on the car bottom may be re,- volved lwhile still engaged by the hook, which action will raise the doorto its closed and locked position.

'Vith these and other obj cctsin view, the invention relates to certain new and novel arrangements and combi-nation -of parts as will be hereinafter more fully described-and pointed out in the claims.

Referring now to the drawings showing a preferredzembodiment of the invention Fig. l is a side'elevation of my improved locking deviceshowing a fragmentary portion of a hopper and hopper door, the door being: shown in its locked position.

Fig. 2 is asimilar view,`the door in this Y instance, however, being in a partly opened and temporarily vsupported position, the

locking mechanism beingrshown in its unlocked position. 1

Y. Fig. `3 is a fragmentary detail bottom plan view of one lcorner ofthe door and hopper and showing a'locking device, and

Fig. 4 is a cross sectional view showing a 70 part of the locking device on each side of the hopper and the cooperatingbar or rod secured to the bottom of the door.

It is to be understood atv the outset that the locking device isv primarily designed for use on hopper cars but maybe usedon other devices having swinging or drop doors.V

Referring now to. the several views,l there 1s Yshown a bracket 1, which is preferably triangular in shape, in which is pivoted at its/upper end, a hoo-lr 2 having the rounded Jaw 3. Alsof pivoted at another angle of the bracket l is the doge which is provided with the outstanding lug 5, while*y at the' opposite angle is positioned a rivet 6 which 95 limits the swinging Vmovement of the hook 2; vThe bracket 1 is preferably formed of two plates, and rivets 7 form the pivotal points for the hook 2 and the dog 4:, the

rivets 6 and 7 also rigidly securing the 90 bracket l to the side 8 of the hopper.

One bracket is secured to each side of the hopper so as' to lock the door-from its opposite/side as will be shortly described.

As willv be noticed in Fig. 4, the edges of 951 the hopper 8 are provided with the short inwardly extending flanges 9 while the bottom 10 of the door is provided with the upwardly` extending flanges 11 which encase the edges 9 of the hopper.

Referring now'to the mechanism which is secured to the door bottom 10, there is' shown the bulb angle or section 12 whichr is securely fastened by the rivetsfl, which angle or section extends transverselylof the entire door 105 bottom and on'which are mounted the bearings 14C` which are also securely held by the rivet-s l5. In these bearings is mounted the rod 16 having the offset portions 17 which,

rest within said bearings., while the ends'18 110 extend beyond the opposite sides of the door as clearly shown in Fig. 4. Y

Also riveted to the door, at its opposite sides, and adjacent the angle 12 are the lugs 19 which act as fulcrum points for a lever or stick to swing the rodv 16. The position of the hooks on the side o f the hopper and the position of the offset ends 18 of the rods 16 is such that the door may be raised by hand until the jaws of the hooks slip under and engage the ends 18 to support the door in a temporary nearly closed position.

At this point, a rod or stick 20, as shown in Fig. 2 in dotted lines, such as carried by brakemen may beplaced between the lug 19 and the end 18 and the rod 16 swung so that the end 18 will assume its lowermost position as shown in Fig. 1 which will of course, force the door against the hopper to tightly close the same and the dog 4 will then be jammed against the rear surface of the hook so that the'` door will be held tightly locked in its closed position.

To open the door the action isreversed, that is the dog' is forced rearwardly by hitting the lug 5 with a hammer and the stick 20 as Shown in dotted lines in Fig. 2 will again be inserted between the lug 19 and the end 18 and the rod 16 revolved so that the offset end 18 will assume its uppermost position as clearly shown in Fig. 2. At this point, the hook may be knocked rearwardly by hand or byl a hammer or bar allowing the door to drop to itsv full open position.

1n the specification, I have spoken about the lever 2O being inserted between the lug 19 and the offset end 18 and it is to be understood that this action may be performed oneither side of the door.

From the foregoing it will be seen that I have provided a locking device which will permit the door to be raised to a temporarily supported position and from which position relatively great force may be exerted by the use of a lever to force the door to its nal locked and closed position, and vice versa.

The locking device is one which is exceedingly strong, easily assembled and easily operated.

Many slight changes might be made without in any way departing from the spirit and scope of the invention.

Havingthus described the same, what I claim as new and desire to secure by Letters Patent is:

1. A car door locking device comprising pivotedy hooks,V said hooks adapted to be secured to the car body, a rod adapted to be mounted on a door, the ends of said rod to be engaged by said hooks and capable 0f an eccentric movement, and adapted to hold the door in a closed position when said ends are in the lowermost position in their path of movement.
